jordan So I was asking about the a770 mainly and UHD 770 which they said will not dither if using true 8 or true 10bit display!! This is really good news. The only thing in question is windows bringing it's own dithering ? But supposedly on arc you can disable windows active color management which would disable os dither right ?
Seagull Its been a while, but in my testing with a capture card + analysis I've not found windows to ever introduce dithering, only GPUs.
jordan Seagull What's weird is a member here tried 1809 vs 2004 and 2004 had pixel flickering while 1809 did not hmm
DisplaysShouldNotBeTVs Seagull windows will definitely introduce its own dithering on Windows 11 2022 Update and later if acm is enabled Windows 10 is less well researched though, not sure about anything related to 10
photon78s Anyone tried this to enable/disable windows 11 acm? https://pureinfotech.com/enable-new-auto-color-management-acm-windows-11/ https://github.com/thebookisclosed/ViVe Once you have the tool downloaded follow the instructions in the first link and run the below in command prompt (admin mode) and restart pc: vivetool /disable /id:36371531 Query to see if ACM is disabled: vivetool /query /id:36371531
photon78s photon78s Even with that tool, I still can't get the acm feature to appear in advanced display settings. Maybe because I'm not on the insider build or previewing latest windows features.

Dadab12 photon78s Same here. I think we both also don't have the Overdrive function in the Vantage software. Do you have CPU overclock in the bios? I'm missing features and I updated the bios to the latest version. So weird.
twomee I also tried to enable acm with my RTX 3060 but without success. Tried to enable it with the command and tried with regedit, both failed. I’m on the latest Windows 11 build. Please let me know if I’m missing something
photon78s twomee I am running windows 11 23H2. It seems it is out of end-user control. At least when I run the query command it says that the "state" is disable for ACM. Have you noticed anything different in the gradient banding test chart? After playing with this tool to enable then disable acm, I no longer notice some slight color shifts in blooey's banding test chart. I notice this when I toggle ditherig settings from disable dithering to enabling spatial dithering. So it seems that I've enabled acm even when it is reported as disabled through vivetool. 🙁
Dadab12 photon78s I see. My bios is KWCN18WW I'm missing so many features and I have no clue what to do. Sigh. I also played with the Vivetool to check for ACM, and I have no idea how I can access "blooey's banding test chart". I tried looking it up but couldn't find anything.
photon78s Dadab12 If you don't see the cpu overclock and other features in bios, then I don't know what is going on. Here is the test chart and instructions on how to use it from another forum member: https://ledstrain.org/d/2686-i-disabled-dithering-on-apple-silicon-introducing-stillcolor-macos-m1m2m3/330
Dadab12 photon78s I can see banding with the ditherig+UHD graphics. Much more pleasant experience. I have instant pain with dGPU now with ColorControl still on. There is no banding… Bah.
photon78s Dadab12 Is the experience still pleasant when you try gaming or anything that activates the dGPU while you MUX bios settings is still in "dynamic"? With ditherig, did you use the "identify GPU by questions..." feature? You may have to do that to make sure ditherig is correctly working.

jordan simplex yeah I haven't even used it yet I'm so afraid of a flareup lol. Mine is the 7i pro i9/4080
